Abstract
An electrical box assembly includes an electrical box having a side wall and an open top end and a conduit access port opening extending through the side wall and having a dimension to receive a conduit. A seal is received in the opening for surrounding the conduit. A clamp is positioned in the opening in the side wall and is positioned between the side wall and the seal for contacting an outer surface of the seal. An actuator is coupled to the electrical box and extends through the side wall into the opening in the side wall to contact the conduit clamp to constrict said conduit clamp and seal into clamping engagement with the conduit.
Claims20
An electrical box assembly comprising:
- an electrical box having an opening with a dimension to receive a conduit;
- a conduit clamping ring coupled to said electrical box for contacting said conduit, said conduit clamping ring having a first free end and a second free end, said conduit clamping ring having a configuration to surround the conduit;
- and
- an actuator positioned for engaging said conduit clamping ring for applying a clamping pressure to constrict said conduit clamping ring into clamping engagement with said conduit when said actuator engages said conduit clamping ring and said second free end moves relative to said first free end to reduce an inner diameter of said conduit clamping ring into contact with the conduit.
An electrical box assembly comprising:
- an electrical box having a conduit opening extending through said electrical box and having a dimension to receive a conduit;
- a substantially cylindrical seal in said conduit opening and having a dimension to surround the conduit received in the conduit opening;
- a substantially cylindrical conduit clamping ring received in said conduit opening and positioned between an inner surface of said conduit access port and said cylindrical seal for contacting an outer surface of said substantially cylindrical seal, said conduit clamping ring surrounding said seal and having a first free end and a second free end;
- and
- an actuator coupled to said electrical box, said actuator extending through said electrical box at an angle to contact said conduit clamping ring and apply a clamping pressure to move said second free end with respect to said first free end to reduce an inner diameter of said conduit clamp and apply a clamping force around said seal into clamping engagement with the conduit.
An electrical box assembly comprising:
- an electrical box having a wall and an open top end and a conduit opening extending through said wall and having a dimension to receive a conduit;
- a conduit clamping ring positioned in said conduit opening in said wall, said conduit clamping ring having a substantially circular configuration with a first free end in a fixed position with respect to said electrical box and a second free end movable with respect to said first free end, said conduit clamping ring having a substantially circular central opening with a dimension for receiving the conduit;
- and
- an actuator coupled to said electrical box, said actuator extending into said conduit opening in said wall, said actuator being movable to engage an outer surface of said conduit clamping ring and reduce an inner diameter of said conduit clamping ring and engage an outer surface of the conduit for clamping the conduit in the conduit opening.
